The Su-37. A photo. History. Characteristics.
Su-37 - fighter used as interceptor any air targets, regardless of size. Even subtle craft with RCS can not stop the plane to get a complete air superiority. The machine is designed on the basis of the Su-35, 1993 and in April, he made his first flight.
This project is interesting because it worked almost all the new maneuvers, such as access to extra high angle of attack and near-zero speed. These include the ability to turn in the pitch plane on 360 degrees (also referred to as "kulbit"), a fixed spread of the battle order in less than 10 seconds, vertical rotation, "Cobra Pugacheva" with an angle of attack 150-180 degree, full turn to " Cobra "," bell "and revolutionized it, the revolution with a small loss of height from the 300 100 to meters.
Most of the technical solutions applied on the plane, provided it:
algorithmic security and multi-channel all sighting and information systems;
without the possibility of entering the air defense zone attack any enemy ground;
low-altitude flight with Walk and Fly ground obstacles;
Group automated actions on ground and air targets;
opposition optronic and electronic means of the enemy;
absolutely all stages of deployment and the flight itself can be executed automatically.
Combines excellent aerodynamic design with CHR (canards), the aircraft is designed on an "integral triplane unstable." Since the original base for the air machine was Su-27, their gliding structure is very similar. However, Su-37 used aluminum casting alloys, the new sample and increased the proportion of composite materials. Especially for the aircraft developed a new wing, which in turn allows you to put more fuel. In comparison with the basic model slightly increased height and the chord of the vertical stabilizer. Secondary fuel tanks steel caissons keels. Since the take-off weight has increased, the need was to strengthen the landing gear and the supply of the nasal support two wheels.
By increasing the amount of fuel the aircraft is able to fly much longer compared to the Su-27. It is because of this it was decided to install a fighter container with a supply of water and food, waste disposal mechanism and add oxygen supply. During the pilot bailout meets new chair CD-36DM (back angle - 30 degrees).
Engineers from design bureau is still at the experimental Su-37 decided to install a motor with a traction control channel pitch. It departs from the engine digital electronic control system, integrated with the control system of all aircraft. At the maximum angle of rotation, and at maximum afterburner on the rotary element of the nozzle for the automatic engine cooling. Due to mismatch thrust direction left and right through the engine thrust vector control possible operation of the aircraft in the pitch and yaw planes. On interceptor installed bar fuel consumer (able to get out) system in-flight refueling.
The design of the Su-37 uses digital FBWCS - electric remote control system. It supports the management of all the control surfaces and the deviation of the thrust vector. In this case the automatic flight safety, as controlled by limiting overload combined flight regime and the masses. In addition, it establishes a mechanism for automatic spin recovery.
On the plane set new hydraulic pumps and power generators that provide increased power consumption of the new CCD (complex avionics).
The complex consists of the avionics subsystems who use elements of artificial intelligence and providing proactive hit air targets, regardless of size. The fighter have established a set of pulse-Doppler radar with fixed antenna, phased array radar and rearview. Su-37 able to detect enemy fighter at a distance of up to 80 100 kilometers. Installed radar carries out the simultaneous detection of air targets and 15 6 management missiles "air-to-air." The structure of advanced optronic sighting system includes a TV and a fighter-designator rangefinder. Radar combined with optical-radar system and is connected to an improved helmet-mounted sight. They are combined into one complex.
Also for group operations on the aircraft we have established a secure system of automatic data about the enemy. It is able to coordinate all the actions of group combat. Defence Complex consists of optical sensors, the pilot warning of incoming missiles, the new station electronic intelligence systems, and active suppression device setting passive infrared and radar interference.
The aircraft is a unified fighting machine, capable, if necessary, act completely automatically, including firing at air and ground targets and counter-optical and radio-electronic warfare. The structure of the radio communications equipment includes HF and VHF, satellite system and telecode connection.
The composition of the weapons originally planned for fighter-interceptor aircraft, but the findings of research and testing have created an opportunity to expand the scope of the plane. The fighter installed automatic single-barreled gun GS-301. It uses cartridge caliber 30 mm, total ammunition - 150 ammunition and firing it at a rate of 1500 rounds per minute. For a complete air superiority, it was decided to use SD-class "air-to-air" with a range of lesions at different distances. In addition, we established a new missile RVV-AE, capable of hitting targets at medium range.
For the destruction of the enemy on land and water meets the complex missiles "air-surface" with different types of guidance. Since the plane can operate equally well both day and night, and missiles must match. X 29T - TV guidance, X-29L - laser-guided Kh-31P - anti-radar missiles, Kh-31A and X-35 - antiship missile applications. In addition, the complex set of unguided rockets, bombs and napalm tanks.
